Yang Xiwen a7982a14b3 i2c: qup: jump out of the loop in case of timeout ... Original logic only sets the return value but doesn't jump out of the loop if the bus is kept active by a client. This is not expected. A malicious or buggy i2c client can hang the kernel in this case and should be avoided. This is observed during a long time test with a PCA953x GPIO extender. Fix it by changing the logic to not only sets the return value, but also jumps out of the loop and return to the caller with -ETIMEDOUT.
